Frigate detection tips

[poxin13]

Any tips on how to get frigate to detect birds better? I've got a 4k camera and have tried various angles, settings, etc but it seems to only pick them up "sometimes" even with what I would consider a very clear and dead-on view on the bird. Love the app by the way this is super cool.

I'm glad you are enjoying it!

Below is part of my frigate config file. Note especially...

      filters:
        bird:
          threshold: 0.6
          min_area: 5000

If you dial down threshold you'll get more detections, but more of them will be false positives. Most of the false positives will be filtered out by WhosAtMyFeeder. Default is 0.7

min_area is by default 0, so setting this to some value greater than 5000 will make sure it isn't flagging tiny little dots as birds.

Also note that in the width and height section under detect I'm feeding the model full sized frames. This requires more processing but should (I think) work better.

  birdcam:
    ffmpeg:
      input_args: preset-rtmp-generic
      inputs:

          roles:
            - detect
            - record
      output_args:
        record: preset-record-generic-audio-copy

          min_area: 5000

Thanks for the info! I did see you updated the readme yesterday with an example but didn't see some of these options in there like threshold. Let me give it a shot with some of these newer options.
